To all whom it may concern.- i

Be it known that I, EDWIN N. WEAVER, a

citizen of the United States, and a resident g of Jersey City, in the'county of Hudson and State of New Jersey, have invented a new and Improved (loal Handling Machine,

of which the following is a full, clear, and exact description. i

This invention relates to coal handling machinery and has particular reference to power operated means for crushing and sizing lump material such as coal having means for conveying the same from the crushing and sizing mechanism to an elevator which serves to deliver the material into an automatic weighing and registering device whence it is dumped into the lower end or boot of an upright conveyer tower from the top of which it is finally delivered through a chute into the bunker batch of a ship, barge, railway car, or other means of conveyance. I v i i Among the ob ect s of the lnvention is to provide means for rapidly handling, sizing,

and transferring bulk material such as lump coal in regulatable quantities from one ship or conveyance to another, as for example in the rapid coaling of ships. or transports.

Another object of the invention is to pro vide a rapid and satisfactory means for transferring coal from a lighter, barge, or other vessel into a sea-going vessel or the like with the employment of practically all power operated machinery, thus dispensing with the necessity for employing many labors, a fact greatly appreciatedat times when .labor is hardito secure andwhen the coalin'g of vessels must be performed in theleast possible time. p Y

With the foregoing and other objects in view the inve'ntion consists in: the arrangement and combination of parts hereinafter described and claimed, and while th'e invention is not restricted to' th e exact details of construction disclosed or suggested herein, still for the purpose ofillustrating a practical embodiment thereof reference is had to the accompanying drawings in whidl like reference characters designate the same parts in the several viewsf,'an d in which-' Figure 1 is a fragmentary plan view partly in section of'a coal handling barge showing the principal parts of invention.

Fig. 2 is a vertical longitudinal section of. the same.

. Fig. 3 is a vertical transverse section on the line 33 of Fig. 2 and on a larger scale. i

Fig. 4 is a vertical transverse section through the elevator tower and indicatin the weighing devicein elevation.

i F ig. 5 is a planview of the sizing plate and crusher actuator; and

Fig. 6 is a vertical transverse section of the elevator drum on the line 66 of Fig. 2. Referring now more specifically to the drawings I show a barge or hull lOof any suitable size, proportions, constructiom'or design but capable of self-support on the water and for carrying .a considerable quantity of coal upon its hopperbottom 11. I-

wish to state at this time once for all'that by the term coal as employed herein I wish to be understood as coveringgenerically. any! analogous lump or pulverulent material. The hopper is co-extensive with a considerable portionof the entirecraft, room being reserved only for the operatingmachinery or the like. The ends of the carrying capacity consist of walls '12 and 13 adjacent to the ends of the barge, andin the end walls 12 and 13 are journaled longitudinal shafts'll preferably parallel to each other and each fitted with'a wheel 15 having a spiral flange or cam 16 formed on its, curved surface. The curves of the wheels on the samershaft are so de'signed'an'd fixed that all parts thereof in directions parallel to the shaft are equally distant. and the cams on one shaft are exactlythe same as those on the other with the exception that those on one shaft are to be presumed Furthermore, the wheels.

from the position of the other. These shafts 14: and the wheels fixed thereto are located beneath the inclined walls or' sections of said hopper bottom so thatthe coal carry ing capacity of the craft is not materially affected thereby. v 7 Extendinglongitudinally and centrally of the bottom of the barge and consequently beneath the hopper bottom 11 is a conveyor shown as of the screw type and having a power shaft 17 to which is secured a spiral blade 18 movable in and along the troug l9 constituting the fixed wall of the conveyer and leadingfrom one end of the hopper to th'e'other, The shaft 17 is journaled in the walls 12 and 13 or in bearings 20 carried thereby. This shaft may be the primary power transmitting member to which power is communicated from any suitable motor indicated as a reciprocating engine 21 at one end of the barge having a connecting" rod 22 attached toIa crank 23. i To the shaft '17 are secured suitable transmission members such as sprocket gears 24 from eaclrof which runs sprocket chain 25 to and over a' similar sprocket wheel 26 secured to the end of a shaft 14 above. described.

Hence the shafts 14: and cam wheels thereon are driven simultaneously with and from the screw shaftl? and all inthe same direction; Thus it will be understood from Fig. 1 the earns of one pair of wheels 15 ap pear to be projected differently from those on the other side of the barge. Inother words assuming the direction of rotation and movement of the parts as indicated-by the, arrows on Fig. 1 allot the cams orspis rali blades 16 will be effective to throwthe crusher actuator and sizing plate 27 in the same direction toward one end of the barge or the other. i I V vSaid plate 27 shown in detail in Fig. 5 comprises a central portion having a pluiulity of holes 28 extending from one end to the other which serve in thenature ofa sieve or sifter when this portion of the plate is reciprocated to and fro endwise of the barge over the stationary sizing plate 29 having holes 30 lying iustabove the screw convey'er and with which the holes 28 are adapted to register at times. At each corner of the plate 27 which is essentially'rectangular is provided an ear 31 having notch 32 into which the adjacent cam flange 16pmj ects and has constant bearing in a direction radial with respect to, the shaft 14. 7 Between the field of the holes 28 and the side edges of the plate 27 are provided on each side a rib 33 and a groove 34 both of which are straight but are flared with respect to each other from one end of the plate to the other, the groove having the greater flare withrespect to the adjacent side edge of the plate, while the rib is slightly flaredavith respect to said edge but in, the opposite direction. In other words while the plate as a wholeis reciprocated to and fro endwise the rotation of the shafts 14E and-wheels connected thereto, devices having engagement ,with

saidsribs and grooves will be given recip rocation in the opposite direction or perpendicular: to the movement of the plate but with different degreesolf throw or am-, plitude; j V

I provide two pairs of crushing j aws, one pair 35 having bars 136 alongftheirremote edges having constant engagement. in the.-

. grooves 34 and which consequently are given a considerable amount of lateral reciprocation toward and 'from each other in the bottom of the hopper for actingupon and re 7 ducingthe largest lumps.- Theteeth 35? of apart than ,tl1e teeth 36", of the" lo werset of jaws whose remote edge tiortionsof rails 37 have constant engagement with the ribs 33 and which consequentlyiare given a transverse reciprocation toward and from each other a shorter distance than the reciproca- 'tions of the aws 35. The purpose of these drum, as shown best in Fig. 2, is antifric tionally supported by ball bearings at l()f and 11 for free rotation under the driving action of a sprocket chain 42 operating over a sprocket wheel 43 connected to one ofthe shafts 14 and, extending around the outside of the drum and in engagement with the sprocket teeth 14 formed thereon; This drum is provided with a plurality of ra V dially disposed partitions 45 subdividing the same into an-cannular". series ot buckets, 46

whichreceivetheir charges of eoallwhile passingbeneathv or along the delivery end oftheconveyertrough 19'. Aguard wall j{l7 extends thence around and upward to a stationary' chute 18' at the top portion. of the drumand to and along which the coal isdelivered from the buckets 4:6 as they come over thesameinsuccession. The entire" interior of the drum 38 ishollow and unobstruct'ed. i -The automatic weighing and registering devices comprise a 'bOX like device lfillhaving one end projecting well intetheinterior of;

the druin 38 and comprisingsidewalls upon: andbetween which is journaled 'on a horizontal axis 50 a rotatable'weighing device having a plurality of blades 51 between each two of which is formed a pocket boundedby the side walls of the chamber 49 andbyvertical wall 52 spaced well7forward' from the elevator drum 38 and opposite the lower end of the chute18/"The rotation of the weighing-device 51- iscontrolledby' two sets of devices, first by V a'catc'h' 53 "c'ompris'ing' fa finger projecting through thejwiall 52 into engagementwith the point or "edgejo-f one of theblades 51- and. -Which" ifs-released" automatically when ande'only when the 'charge of coal received upon such "blade between the chute 48 andth'e wall 152 is equal 'to' pre determined amount according-to the adj ust ing' or setting-of a weigh-t' 53i. I 'l/Vhen the desired charge of coal is thus received the catch will be automatically released and sibility of reverse rotation thereof. This catch device 53 may be adjusted with precision and will always act to deliver predetermined quantities of coal at each actuation of the rotary device. A counter 54 is actuated to make a record of such fact so that at the end of a certain period of time the total number of weighed charges will be indicated.

when the loaded pocket 51 of the weighing device is to be dumped the coal therefrom will pass directly into the boot portion 55 of the bucket elevator which comprises a tower 56 having up and down legs on opposite sides of the weighing device and the chamber 19 and along which an endless series of buckets or flights 57 operate over and between a pair of head wheels 58 at the top of the tower, and with a sprocket wheel 59 connected to the axle 60 of said wheels. A sprocket chain 61 or its equivalent operates f om a sprocket wheel 62 on one ofthe shafts 14 to and over the wheel 59 for operating the endless chain of buckets or flights and whereby the coal deliveredinto the boot 55 from the chamber 19 or weighing device pockets is picked up automatically and carried upward along the up leg of the tower and dumped between the wheels 58 into a chute 63 the lower end of which may be adjustable in any direction to determine the point of delivery of the coal.

Thus it will be seen that from a single power plant located at any convenient place in or upon the craft I am able witha minimum amount of manual labor or attention to discharge quickly an entire load of coal, preparing it without hand pulverizing or crushing for the feeding of boilers or other furnaces and delivering it also in a weighed and quantity determined condition.

I claim 1. In a coal machine the combination of a bottom, crushing means beneath the bottom serving to crush large lumps and facilitate the delivery of the material-therefrom, a combined crusher actuator and sizing plate beneath the crushing means, means to reciprocate said actuator and plate, means between the crushing means and said actuator to cause the actuation of thecrushing means in directions transverse to the direction of movement of the plate and actuator,and means to deliver the crushed coal after it passes through the sizing plate.

2'. In a coal machine the combination of a bottom, a plurality of pairs of crushing jaws beneath said bottom, the jaws of each pair being movable toward and from each other, a crusher actuator beneath the jaws, and means to operate the actuator, connections between the actuator and the aws to causereciprocation of the jaws of one pair in directions opposite to that in which the other jaws reciprocate, the actuator being moved in directions perpendicular to the directions of the movement of the jaws.

3. In a machine of the class set forth, the combination of a horizontal plate provided along its longitudinal center with a series of sizing holes and having on opposite sides of the holes a pair of ribs extending lengthwise of the plate, but slightly divergent from each other and having on opposite sides of the ribs a pair of longitudinally extending grooves divergent from each other to a greater extent than the ribs and in the opposite direction, means cooperating with the plate to reciprocate it endwise, and two pairs of crushing jaws located above the plate and cooperating with the ribs and grooves respectively whereby they jaws of each pair will be reciprocated transversely grooves.
